To define the three court systems in the United States, we first need to understand how power is shared. In the U.S., we have two main types of government: federal and state. Each of these has its own courts. And then there’s a third one, called local courts, which handle things like traffic tickets or city laws.
So here it is:

- Federal Courts – These deal with national laws.
- State Courts – These handle state laws and most everyday problems.
- Local Courts – These are small courts for towns or cities.
Now let’s go a little deeper into federal courts. One important part of this system is the U.S. District Court. So let’s describe U.S. district courts in plain terms.
A U.S. District Court is the starting point for most federal cases. It’s where trials happen. This is the only federal court where witnesses testify, juries decide, and judges give rulings. Every state has at least one district court. Bigger states have more. These courts handle cases like bank fraud, drug crimes, and anything that breaks a federal law.
So far, we’ve seen the US court system explained in simple words. You now know how to define the three court systems in the United States, and you can even describe U.S. district courts with confidence.
In the next section, we’ll compare state courts vs federal courts with easy examples you’ll relate to.
State Courts vs Federal Courts — What’s the Difference?
Now that you’ve seen the US court system explained in simple words, it’s time to talk about a very common question:
What’s the difference between state courts and federal courts?
Let’s break it down using real-life situations.
Imagine someone steals a car in your town. That case will probably go to a state court, because it happened within one state and breaks a state law.
Now imagine someone robs a bank that is run by the federal government. That’s more serious. It breaks a federal law, so it goes to a federal court.
So, what makes them different?
State Courts:
- Every state has its own court system.
- They handle most problems people face.
- Cases like robbery, divorce, child custody, traffic tickets, and property fights are handled here.
- About 90% of all court cases in the U.S. happen in state courts.
Federal Courts:
- These are national courts created by the U.S. Constitution.
- They deal with federal crimes, the U.S. government, and problems between states or different countries.
- They also hear cases about immigration, Social Security, or big fraud cases.
Here’s a fun way to remember:
If the problem is local, go to state court. If it’s national or crosses borders, it’s for federal court.
This side-by-side look helps you understand the US court system explained in simple words. It also shows how state courts and federal courts work together but handle different things.

In the next section, we’ll meet the people who help decide the cases, the jury. We’ll look at trial jury vs grand jury, and why they matter.
Meet the Jury — Trial Jury vs Grand Jury Made Simple
We’ve now seen the US court system explained in simple words and how state and federal courts are different. But who actually decides if someone is guilty or not? That’s where the jury comes in.
In the United States, there are two types of juries — the trial jury and the grand jury. These are regular people like you and me who help decide legal matters.
Let’s make it easy.
What is a Trial Jury?
A trial jury is sometimes called a petit jury. This group sits in the courtroom during a trial. They listen to both sides — the person who is accusing and the person who is defending.
Once the trial is over, the jury leaves the room to talk in private. They discuss what they saw and heard. Then they decide the outcome — guilty or not guilty.
Key facts about a trial jury:
- Usually has 6 to 12 people.
- Works in both criminal and civil cases.
- The decision they make is called a verdict.
- The jury must agree on the verdict in most cases.
What is a Grand Jury?
A grand jury works differently. They don’t decide guilt. Instead, they ask this question:
Is there enough evidence to charge someone with a crime?
If yes, they issue something called an indictment, which means the person will face trial later.
Key facts about a grand jury:
- Usually has 16 to 23 members.
- Only the government lawyer presents evidence.
- The public and the person accused are not in the room.
- Used in serious federal crimes.
Both juries are important in giving fair justice. This is one more part of the US court system explained in simple words.
Real-Life Examples — Which Court Handles What?
You’ve come a long way! You now know how the US court system works, the difference between state and federal courts, and how juries help make decisions. In this part, we’ll test your understanding with some everyday examples.
Think of it like a quick game. For each case, ask yourself — Is this for a state court or a federal court?
Let’s begin.
1. Murder Case
A person is accused of killing someone in their hometown.
Answer: State Court
Why? Most murders break state laws and happen in one state.
2. Tax Fraud
A person lies about their income on their federal tax return.
Answer: Federal Court
Why? Taxes like this are collected by the U.S. government, so it’s a federal law violation.
3. Divorce Dispute
A couple wants to legally separate and fight over custody of their child.
Answer: State Court
Why? Marriage and family laws are handled at the state level.
4. Kidnapping Across State Lines
A child is taken from one state to another without permission.
Answer: Federal Court
Why? It involves more than one state, so it’s under federal jurisdiction.
5. Traffic Violation
You run a red light and get a ticket in your city.
Answer: Local/State Court
Why? Traffic laws are made and enforced by the state or city.
This quick quiz shows how different situations fall into different courts. When you see the US court system explained in simple words, it all starts to make sense, right?
Why You Might Be Called for Jury Duty
You’ve now seen the US court system explained in simple words — from the types of courts to how juries work. But here’s a question many people ask:
Why do I get called for jury duty?
Let’s make it easy to understand.
What is Jury Duty?
Jury duty means you are chosen to be part of a trial jury. You sit in court, listen to a case, and help decide the outcome.
The government randomly picks names from voter rolls or driver’s license lists. If your name is picked, you’ll get a letter or notice in the mail.
You don’t have to be a lawyer or expert. In fact, juries are made up of regular people from the community. That’s the idea — justice should be decided by the people, not just judges.
Why is Jury Duty Important?
- It’s part of your civic duty, like voting.
- It gives people a fair trial, with decisions made by a group.
- It keeps the system honest and balanced.
What Happens If You’re Called?
- You may have to go to court for a day or a few.
- You’ll be asked questions to see if you’re a good fit for the case.
- If selected, you’ll serve on the jury and help reach a verdict.
Yes, it can take time, but it’s a big part of how the court system works. It’s how you become part of justice in action.
So when we talk about the US court system explained in simple words, jury duty is a major part. It’s about fairness, trust, and giving everyone a voice.
How the Court System Affects You Every Day
Now that you’ve seen the US court system explained in simple words, you might be wondering — does this really matter in my daily life?
The answer is yes. The court system is not just something you hear about on the news. It touches your life in more ways than you think.
Renting a Home?
If your landlord tries to force you out without notice, you can go to small claims court. That’s a local court. It helps protect your rights as a renter.
Buying a Product That Doesn’t Work?
Let’s say you bought something expensive that broke right away. You can take the seller to court. This is usually a state court case, under consumer law.
Facing Family Problems?
Divorce, child support, and custody battles all go through state family courts. These courts help solve sensitive, emotional matters.
Work Problems?
If you’re treated unfairly at work, like facing discrimination or not getting paid, some cases may go to federal court, especially if federal labor laws are broken.
Hurt in an Accident?
If someone injures you and it wasn’t your fault, you can sue for damages. These personal injury cases usually happen in state courts.
So, whether you’re renting, working, shopping, or raising a family, the courts are there to make sure things stay fair.
This is the US court system explained in simple words — not just theory, but part of your real life.
